Hi! I do it every week. It's a little challenging but it can be done. You can hit a chord on the keyboard, leave it sustained, do a little run on your sax, then release and change chords when appropriate. It's just a little more challenging with the organ, however, since a real organ doesn't have a sustain pedal. You pretty much have to intermittently do organ runs and fade out when you want to come in on the sax, or you can do organ all the time with your right hand and a limited amount of notes on the sax with your left hand. Since neither instrument is playing the melody of the song all the way through, it's quite do-able and it can sound very good. Sometimes we have to do what we have to do when there are fewer musicians than instruments! (Not to mention, it's sometimes kind of fun when you have people scratching their heads wondering how in the world you do it! LOL!)
